Once the Earth Skylanders reached the castle, Diggs explained that the Crystal Eye made his blurry vision completely clear. He also informed the four that they needed to destroy two Seeing Towers to open the gate leading to the Crystal Eye. Before he could say something very important, he was knocked down by rolling barrels! As Timidclops rolled the barrels down, Terrafin burrowed, Dino-Rang used Stonefist Traps to block them, Prism Break used his lasers to destroy them, and Bash used his tail to deflect them. However, when the four of them reached the Cyclopses, instead of fighting them, the cowards leaped off the edge! "Wimps." Terrafin said, secretly hoping for a fight. However, he knew he would get one soon. Then suddenly, out of a few barrels, blue Chompies attacked! "GAH!" Dino-Rang yelled. "Get them off me!" As the Chompies, called Crunchers, latched on with their razor-sharp teeth, Terrafin was able to shake them off by grabbing some and throwing them. With their rock-hard skin, Bash and Prism break hardly felt a thing. As they finished the Crunchers off and traversed up another ramp, Cyclopses with axes attacked, Dino-Rang's Stone Boomerangs were deflected by the spinning, and he threw them again when the Cyclops was dizzy. Then, after all the enemies were dealt with, Terrafin had a plan. "Ok, two of us will take the East Seeing Tower, while the other two take the West Seeing Tower!" He said. When Terrafin and Dino-Rang went into the East Tower, they found it guarded by a giant Cyclops Mammoth! Roaring angrily, it broke free of its post and lunged. With their weapons and powers, the two were able to defeat the beast. Then, Terrafin got an idea. "If we destroy those beam projectors, we should be able to destroy that pylon, which should be able to destroy this tower." After the pylon was destroyed, the two got out of there as fast as they could. Bash and Prism Break had just done the same thing at the West Tower. Now, it was time to get the Crystal Eye! However, as if knowing the Earth Skylanders would come, the Cyclopses had prepared their defenses. Cyclops Chuckers were on pillars, Mammoths were unleashed, Timidclops were staying back (due to their cowardliness), and Choppers and Crunchers were as the main defense. After many punches, pummels, stone fists trappings, and laser beams later, the Crystal Eye was finally gained. Now, it was time to head back to the Ruins and add it to the machine.
"Well done!" Eon congratulated. "You have brought the Crystal Eye!" Terrafin threw the eye into the spouts like a volleyball. After it was placed in, something was heard underground. Something like a crystal being forged. Now, all that was left was the Eternal Earth Source. According the Hugo, it was kept in Stonetown. The villagers there kept it safe until the Skylanders would arrive. Luckily, Diggs knew the way. The bridge that lead to the castle split two ways. The way back was towards the Ruins, the way right was to the Crystal Eye Castle, and the way left was towards Stonetown. When the Earth Skylanders went there, something told Terrafin that something would go terribly go wrong.
